Reversing means for internal-combustion motors



Nov. 29, 1927. c.. F. SJMAN ET AL REVERSNG MEANS FOR NTERNAL COIBUSTION MOTORS Filed June 17. 1924 aeelnne its normalposition. Tlle lever 1T also follows backwards, its book-litre projection 18 beingy tllen disengaged from tbe bool: 19.A After tbe lever llas tlllls been released, it willvbe turned bark by tlle spring 2t), so tllat tbe projection 18 ie elevated in ,trent of tlle llook 19 and abats against tlle latter so as to retain the parts-in tbe position of normal running'.

The arrangement may evidently be modified with .respect to tlle details tllereol witbont departing" :from talle plineiple ot tbe illvention. Thus, illplflee of tbe lever 17, `@eine other means may be need to lllove tlle pump pistolntm instance a Spring` acting,r on tlle pllnlppieton, sllell spring being! so al'- raneed neto be brouellt into operation as Soon as tlle piston llasbeeollle 'tree for being' displaced lorlvarlls by tbe lowering ol tbe part 18.

that we elainl as new and deeire to eeellre by Letters Patent ot tlle United States of America is: i

1. In oonlbination, an inertia tappet adaptA ed to be constantly operated by all internal combustion engineldlll'ing working et tbe latter, a fuel pump for tlle ellglfille` constantly operated by tlle tappet duringy Working;- of the engine and eonlprising` a pieton nlenlbel-and a cylinder .memllelg means 'tol' adjusting one ot said menlberf'irelatively to tlle tappet to Cause tlle actuator to operate tbe adjusted member earlier tllan under normal Conditions.` ero as to brine" about tlle pren'ultllre ignition required 'lolj` tlle reversal ot the engine and means connected to said eylinder for causing' tlle etl'eetive etiolle o't talle. piston to remain constant.
